IM PROVEMENA'I'l IN WATER-REGULATORS.

Specification forming part of Letters Patent No. 136,024, dated February 18, 1873.

To all whom it mayvconeern:

Beitknownthatl,JAMESRBOLIN,ofOrangeburg county, South Carolina, have invented certain new and useful Improvements in Water-Regulators, which are simple in construction, eleient in operation, and durable in use; and it consists in hinging or pivoting gates of different sizes above the mill-breast, by which means the surplus water is dischargedV and the gates are automatically opened and closed, being an improvement upon the ordinary single gate now in use, by which the whole space of the millbreast is opened and closed, allowing a large and violent current of water to be discharged when only a small current is necessary, ,whereas by my improvement the amount of water discharged is automatieally'regulated to correspond to the rise of the water; and I do hereby declare that the following is a.ffull, clear, and. exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing with letters of reference marked thereon forming a part of this specification, in which- Figure l is a front elevation of a device enr bodying my invention; and Figi2 is a vertical section7 showing one gate open.

A A A are gates of different sizes, suitably pivoted or hung upon axles having bearings in the upright standards (l. B B represent cleats .secured to the posts G for the gates A to close against. G C represent the upright standards, having the cross-bar E at the top and secured to the floor D at the bottom. F represents the ordinary walling at the sides, and G the mill-breast. H represents the mill breast bottom.

The construction of the framework above may be of any suitable or convenient construe tion without departing from the spirit of my invention.

'The gatesV are made of' different sizes, as shown, so that as the gwater rises the smaller gate will open irst, which may besuicient to discharge the surplus waterf It not, and the water continues to rise, the next gate in size opens, and so on until the Water rises until the gates are all opened; then, as the water falls, the gates close in the same order as opened until the water falls to the ordinarylevel, and thus, by the automatic movement of the gates, the rise and fall, of water-'are regulated as it rises and falls.

'Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, is- The gates A A A, of different sizes, hinged or pivoted between the posts C above the millbreast bottom H, all constructed and arranged to operate substantially as and for the purpose herein specied.
